All three of these drugs function in the same way as they cause a large increase in acetylcholine, a brain neurotransmitter, to allow the undamaged cells of the brain to function at their fullest potential causing a slight reverse in damage to areas such as short term memory. There is also evidence to suggest these drugs prevent the build up of toxins in the brain, improving the overall functioning of the brain. While these drugs have a high success rate in people who suffer from brain diseases there is very little proof to suggest they have any enhancing effects on healthy people. These three drugs, much like the Ampakine drugs, have no known side effects making them a favored choice of treatment by many physicians dealing with patients suffering from brain diseases such as Schizophrenia, Alzheimer and Parkinson's disease.
Scientists test the effectiveness of these drugs in treating patients with diseases altering brain chemistry and subsequently impairing short term memory by running a series of tests such as the non-match to sample test as well as the maximum capacity test which involves viewing a series of images and remembering them in order until you've reached your maximum capacity of short term memory. This tests were conducted before and after treatment with the drugs as an increase in response time and maximum short term capacity was then established within the patients.
Below is a mind map summarizing the main qualities of these drugs in relation to short term memory.
